80 Series Landcruiser Factory-to-ARB Air Locker Control Module Adapter

Run your ARB air lockers using the factory 80 Series diff lock switch.
Plug-and-play install, factory dash light integration, and zero wiring mess.

Upgrade your 80 Series to a true OEM-style locker setup without the hassle of messy wiring and rocker switches. While factory diff locks were only optional, every 80 Series came pre-wired to support them—allowing this module to integrate seamlessly with your vehicle’s existing wiring system.

This control module bridges the gap between modern ARB air lockers and Toyota’s factory controls, letting you operate your lockers directly from the original switch while activating the factory dash indicator lights.

The unit supports both single and twin locker configurations and is completely plug-and-play. One connector plugs into the factory Toyota diff lock ECU outlet, while the other connects to the standard 4-pin ARB compressor plug. No cutting, soldering, or crimping is required.

Bolts directly to the factory mounting points inside the passenger-side kick panel—no drilling required.

Note: Factory Toyota diff lock switch (Part No. 84725-60020) is not included but is widely available.
